1-letter-apps (diary, notes, rowing, sittings, todos, expenses)

I maintain and use a couple of 1-letter-apps.
They all are minimalistic (progressive) web apps that solve a single purpose:

• d - Track your diary entries on the go. (Repo)
• n - Save and edit notes with heading and body. (Repo)
• r - Track your rowing sessions on the go. (Repo)
• s - Save, edit, and delete meditation sittings. (Repo)
• t - Save tasks on the go. (Repo)
• b - Track your expenses on the go. (Repo)
• m - Create mailto links. Paste mailto's and edit. (Repo)

They all follow the same pattern:

• No user account, save data on device (via LocalStorage)
• No backend, just HTML + JS
• Allow copying as structured data to clipboard (via JSON or Markdown)
• Have basic CRUD for all data
• Use AlpineJS for logic
• Use TailwindCSS for styling
• Installable PWA
• No translations
